Abstract

Chronic diseases have a significant impact on patients' quality of life, physically, psychologically and socially. Optimism, as part of positive psychology, plays an important role in helping patients face health challenges and improve their well-being. Objective: To identify the relationship between optimism and quality of life in patients with chronic diseases through a systematic review. Method: Following PRISMA 2020 guidelines, a comprehensive search across databases such as PubMed, Scopus, Sage, and Nature identified 7,340 articles, with six studies meeting the inclusion criteria. The review included only full-text, English-language quantitative studies—specifically case-control, cross-sectional, cohort, randomised controlled trials (RCTs), or quasi-experimental designs—that examined the relationship between optimism and quality of life in patients with chronic illnesses. There were no restrictions on publication year. Exclusion criteria comprised review articles, meta-analyses, and book or book chapter publications. Each included study was critically appraised using the CASP tool, which assessed research objectives, study design, sampling methods, measurement validity, bias control, and data analysis to ensure methodological rigour. Results: The analysis showed that optimism was positively associated with improved quality of life, especially in physical aspects such as reduced fatigue and improved mobility, as well as psychological aspects such as emotional and spiritual well-being. Social support also strengthened the impact of optimism on quality of life. Community-based interventions, occupational therapy, and multimodal approaches proved effective in increasing patient engagement in meaningful activities. Conclusions: Optimism is an important factor in improving the quality of life of chronic patients, and optimism-based interventions can be an effective strategy to support holistic patient well-being.

Abstract

Cancer-related fatigue is one of the most frequent symptoms and has a significant impact on the quality of life of cancer patients. Accurate fatigue measurements require instruments that are valid and reliable, and appropriate to the cultural and linguistic context. Therefore, it is necessary to test the validity of the construct and reliability of the Indonesian version of the Cancer Fatigue Scale (CFS) before it is widely used. This study aims to test the validity of the construct and reliability of the Indonesian version of the Cancer Fatigue Scale (CFS) instrument in measuring fatigue in cancer patients. This study is an analytical descriptive research using a Cross Sectional design. This research was conducted at Darmais Cancer Hospital (RSKD). The number of samples was 220 people, with a sampling technique, namely purposive sampling. The instrument used in this study was the Cancer Fatigue Scale (CFS) as the core questionnaire. The data was analaysed to test realibility and validity of instruments CFS.   The results showed that all Indonesian version of CFS items had a total item–correlation value above the minimum acceptable limit (r > 0.30), indicating adequate construct validity. The reliability test showed Cronbach's alpha value of 0.824, which indicated good internal consistency. The Indonesian version of the Cancer Fatigue Scale has been proven to have good construct validity and reliability, making it suitable for use as an instrument for measuring fatigue in cancer patients in oncology nursing research and practice.
